From what I can deduct, you are probably referring to a pre-built car that is 2014MY, new orders are now 2015MY and some of the things that were option on the 2014MY are now standard on the 2015MY.
I also deduce that you are referring to a regular S5 and not a S5 Black Edition.
On that basis my answer to your questions are as follows:

The Car is an S4 59 plate. How does this effect the above?
Can the TV be retro fitted as it's not on the above car, something I spotted on another car.
Is the sat nav on the above a MMI 3G HDD the type that can do 3d maps?
